4-2-6. T-CON Board
T-CON Operation and Testing
Check TV Board Connector Voltages from SMPS (switched voltages on CNM803)1.
Test for 13VDC at both sides of both fuses on the TCON Board.2.
If either one of the fuses is open, replace the T-CON Board.3.
If 13VDC are missing on fuses, check output feed from TV Board (CN501,pins 1-10).4.
If 13VDC feed is present at the output of the TV Board, suspect a defective LVDS cable.5.
If the 13VDC feed is not present, suspect a defective TV Board or SMPS.6.
